Given data:
Number of poles (p) = 6
Number of conductors (N) = 300
Flux per pole (φ) = 15 mWb
Speed of the machine (N) = 1800 rpm

To find: Average emf induced per conductor

Formula:
The average emf induced per conductor in a DC machine is given by the formula:

E = (φ * N * p) / 60 A

where E is the average emf induced per conductor,
φ is the flux per pole,
N is the speed of the machine in rpm,
p is the number of poles, and
A is the number of parallel paths.

Since it is a DC machine, the number of parallel paths (A) is equal to 1.

Calculation:
Substituting the given values into the formula:

E = (15 mWb * 300 * 6) / (60 * 1) V
E = (15 * 300 * 6) / 60 V
E = 2700 / 60 V
E = 45 V

However, the question asks for the average emf induced per conductor, so we need to divide the result by the number of conductors (N).

Average emf induced per conductor = E / N
Average emf induced per conductor = 45 V / 300
Average emf induced per conductor = 0.15 V

Therefore, the average emf induced per conductor in the given 6-pole DC machine is 0.15 V, which is equivalent to 2.7 V (rounded to one decimal place).

Hence, the correct answer is option B) 2.7 V.
